T0 all wkom z'25 mag conce1m:

Be it known that we, FRITZ KOCH, a citizen of Germany, and residing et 35 Heidterstrasse, Oronenberg, Rheinland, Germany, and RICHARD POHLMANN, a citizen of Germany, und residing at 37 Heidterstrasse, Oronenberg, Rheinland, Germany, have invente'd certain new and useful Improvements in e SaW-Sebfiing Machine (for which We have filed application in Germany, 11th Feb ruary, 1924;), of Which the following is a specification.

The invention provides the hereinafter described und claimed improved saw setting machine.

Saw setting maehines are known in which seveml teeth are set at the same time. The punehes and dies used With these known lilachines a1e made in 0ne piece and saw sett1ng aceomplished With tools of the known type calls f01 great aceuracy and much time is wasted in making adjustment.

The objeet of the invention is a machine to overcome the disadvantages stated and costly punches and dies, ere avoided by the punch and the die being made adjustable independently 0f each other by tW0 wedges.

In the annexed dravvings a desirable embodiment is illustrated.

Fig. 1 is a VieW of the machine in part section a1ong the line A. B. of Fig. 2 Whieh is a front view 01 the machine.

Fig. 3 illustrates the two parts for the die and punch.

Fig. 4 is e top view of the wedge.

Mounted upon a known machine is a revo- Iuble cam a adapted to work in contaet with a roller b situated above the cam a and by the revolution of the cam, which in this embodiment is of the snail type, the slide c is actuated up and down. In the lower part 0f the slide 0 is provided a gap into Which the two adjacent parts of the punch 0Z and e are clamped by the aid 0f the p1ate f and the screws g. Near this gap e boring z is located adapted t0 receive the wedges ]Z1, h, disposed transversely through the slide. The wedges lie against the edges of the c01'1e spondingly s1oped punch parts a? and e and a1e rigi'dly fixed by screw bolts k. By the use of a, punch of this construetion it is pos- Sib1e 130 adjust each part to its proper height for acting upon the teeth of e .saw. The die located below the slide is similarly coustructed.

The die shoe has a gap therein similar t0 thet provided in the slide 0 und into this gap the parts 03 e constituting the die tools are clamped by the aid of the plate Z and the screws m. Disposed below seid parts is a boring 0 transversely located to the gap aforesai'd which boring serves. to accommodate the wedges n n which are adapted 130 be c]amped by the screw-bolts p so that the two parts al e constituting the die can be adjusted independently of each other.

The tools constituting the die and those disposed below constituting the punch are arranged in such relation that when the s1ide 0 descends through the revolution of the cam a acting upon the roller b one tooth 011 a saw is struck in an upward direction by the eine pair of tools and the adjacent tooth is struck in a downwar'd direction.

The construction of the die and the punch each being in tvvo parts provides a very simple means for tbe purpose 0f saw setting end moreover any slight inexactitude can be quickly corrected by means of the wedges hereinbefore described so that an even setting can be continuously provided.

What we c1aim is:

l. A saw setting maehine comprising in combination a vertical frame, a slide member arranged therein, means for reciprocating the slide member, a, punch earried by the slide member consisting of two removable arts, a die shoe arranged below the slide member, a die consisting 0f two removable parts disposed Within the die shoe charaeterized in that by the operation of the punch upon a saw inte1posed between it and the die adjacent teeth are displaced 130 the 1eft and right by a sing1e passage of the saw through the maehine 2. A saw setting machine comprising in combination a frame, a slide member vertieally arranged therein, means for reciproeating the slide, two removable parts arranged in the slide constituting a punch, two removable pa1ts housed Within a die shoe constituting a die, there being a gap iocated in the slide to receive the parts constituting the punch, there being a gap located in the die shoe to receive the part constituting the die, means for clamping both the punch und the die to the s1ide and shoe respectively, there being a transverse bore open ing into each of sai'd gaps, wedges loeated in said borings t0 lie against the shaped edges cf the parts constituting the punch and die and means for clamping the wedges so that each may be independently adjustable substantially as described. 10 In testimony whereof we have signed 0111 names t0 this specification.
